BOTTLE.

SPECIFICATION forming part of Letters Patent No. 621,112, dated March 14, 1899. Application filed April 1, 1898. Renewed February 3, 1899. Serial No. '704,435- (NO model-3 T0 all whom t may concern:

Be it known that I, PHILIP LINDEMEYR, a resident of Baltimore city, in the State of Maryland, have invented cert-ain new and useful Improvements in Bottles; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable' others skilled in the art to which it pertains to make and use the same.

The invention relates to that class of capstoppers for bottles and the like which are secured by a bayonet-joint 5 and it has for its objects to improve the cap and bottle, to secure a tight closure that can be easily effected and renewed, and `to avoid certain objections to prior devices.

The invention consists in the construction hereinafter described and pointed out.

In the accompanying drawings, Figure 1 is a side elevation;Y Fig. 2 is a central section of a bottle neck and cap embodying the im- Fig. 3 is a central section-of the cap. Fig. 4 is a plan of a blank for forming the cap. Fig. 5 is a broken perspective showing the interior of the cap. Fig. 6 is -a central section showing modified bottle-lip. Fig. 7 is a detail showing groove of bayonetjoint, and Fig. S is a detail showing modified bottle-head.

Numeral 1 denotes a bottle having a neck 2, provided with a shoulder 3 and a head or terminal A of less diameter than the neck proper. This shoulder may be made a continuous incline, asindicated in Fig. S.

5 denotes a metal cap having a groove 7 to receive wax or wax and cork or other packing substances and provided with corrugations 6, which afford a secure hold for the manipulation of the cap and also providegrooves on the inside vto receive and hold packing.- The cap has a shoulder or offset 8 similar to that on the bottle. Below this offset the cap is corrugated to facilitate manipulation except at the parts adjacent the bayonet-joint grooves 9, formed in the bottleneck. It is corrugated above the shoulder preferably around the whole circumference.

10 indicates lugs formed in the iiange or collar 11 of the cap. These are equal in number'and similar in situation to the grooves 9 and are adapted to be entered therein and to be engaged with the upper wall of the inclined part of the grooves by suitable rotation of the cap.

The lugs 10 may be produced by Iirst slitting the blank from which the cap is subsequently formed, as indicated at 12 in Fig. 4. After the cap has been formed in usual manner and applied to abottle-neck the strip between the slits is forced inwardly to form a lug 10 with a sharp bearing edge having throughout its length the saine angle of inclination as the inclined part of a bayonetjoint groove, and therefore adapted to bear throughout its entire length on said part. The grooves are situated below the bottlehead and begin in the shoulder 3 ory 3. (See Fig. 8.) In the latter figure the slot is indicated by a dotted line terminating approximately at the mid-height of thel incline and below the possible reach of the cork or other packing. Heretofore in analogous constructions the grooves have extended to the bottle mouth or lip--that is, to the upper end or mouth of the bottle-and this construction has been found objectionable for reasons to be explained.

14 denotes a thin layer or lining of cork,

'and 15 indicates wax, and these materials together constitute a packing between the loottle mouth and cap. In applying the cap provided with a cork lining or packing whether the wax be used or not it is desirable the cap be held tightly upon the bottle and the cork compressed upon its mouth. A considerable degree of force is required to suitably compress a cork packing upon an ordinary bottlemouth to secure a tight joint, because of the `thickness of the glass, which necessitates a cap the lining is not disturbed by contiguous y 'edges or corners 16 at the upper ends of the bayonet-grooves, as in prior constructions, in which said grooves extend to the lip and to the cork when held on the bottle-month by a cap. If the cork were pressed directly upon a grooved mouth, a portion of it would be forced into the grooves, With the result that when the cap was unscrewed the cork would be torn. The cork would also be loosened, so as to drop from the cap. Both of theseeffects are highly objectionable and especially in a cap designed for reuse, as in the present case.

A bottle-mouth havinga continuous lip unbroken by grooves is more suitable for application to the mouth in drinking, and particularly in the case of children. Such grooves extended to the lip interfere With drinking and in some cases tend to spilling and may also hurt or annoy the lips of the one atte1npt ing to drink from them. This evil is incidentally avoided in bottles of the class to which the improvement relates.

In applying the cap provided with a compressible packing it is forced down upon the bottle-mouth, so as to compress the packing, whereby the bottle-lip is entered in the annular depression caused by the said lip. The lugs IO are simultaneously entered in the grooves and turned to bring their upper edges under the upper wall of the inclined portions of the grooves. The cap being thereupon released f rom the pressure required to effect this connection, the elastic packing Will expand sufn'ciently to cause the lugs to engage the groove-Wall. This engagement extends the whole length of the lugs in consequence of the similarity of the inclined proximate surface. As the bearing-surface of each lugincline is a metall edge driven against the groove-wall by the elastic packing, provision is thereby made for a large degree of friction to resist the rotation of the cap and its accidental removal. The cap and its packing, however, can be forced down upon the comparatively sharp lip edge of the bottle to recompress the packing and permit its easy removal by rotation, the edges of the lugs being thereby released from close engagement with the Walls of the grooves. In such rotation the cork is held securelyin the corrugations of the cap, and, further, it is not injured or loosened by the entire bottle-lip, as would be the case in a grooved lip.

The particular form of lug is preferred for several reasons. It can be marked out by slits made in the blank, which render the subsequent forming ofthe lugs an easy operation as compared with lforming them from uncut metal, Which requires too much force for the safety of the bottle when formed with the cap in position on the bottle-month. Further, a lug cannot be provided with a bearing edge such as herein described by mere indentation of the metal. It is essential to the improved combination that a sharp edge of comparatively stilf metal be drawn throughout its entire length against the groove-Wall to provide sufficient friction.

The slits are not necessarily made in the flat blank, but can be made in the flange of the cap after it has been formed.

In some cases the bottle-lip will be beveled, as indicated in Fig. 6, to insure an edge that can be forced into the cork conveniently and produce a tight joint. These and other modiflcations not involving a substantial departure from the improvement may be adopted in the manufacture of the cap.

Having described my invention, I claim;

l. The combination of a bottle having a neck provided with a continuous circumferential shoulder constituting its upper end and a head of less diameter than said neck, the

.latter having bayonet-j oint grooves each with an inclined circumferential part and a vertical part beginning in the shoulder below the bottle-lip and cork-seat, said groove terminating in the'enlargement, with a cap pro vided With a similar shoulder, a cork or other packing seated on the bottle-lip, and lugs in the cap below its shoulder to engage said bayonet-joint grooves whereby When the cap is screwed down the cork is drawn upon the lip Without entering the groove, substantially as described.

2. The combination of a bottle having a neck provided with a continuons circumferential shoulder constituting thc upper end of a neck enlargement, a head of less diameter than said neck and bayonet-joint grooves beginning in the shoulder and terminating in the enlargement, with a cap provided with a similar shoulder, and lugs below the cap-shoulder to engage said bayonet-joint grooves, said lugs having sharp edges with inclination ap proximately similar to the inclined walls of the grooves, substantially as described.

3. The combination of a bottle having a neck provided with a continuous circumferential shoulder constituting the upper en d of a neck enlargement, a head of less diameter than said neck and bayonet-joint grooves `be ginning in the shoulder and terminating in the enlargement, With a cap provided with a similar shoulder, lugs bcloiv the cap-shouldcr to engage said bayonet-joint grooves, and vertical corrugations formed in the enlarged part of the cap-iiange intermediate the lugs, substantially as described.

4c. The combination of a bottle having a neck provided with a continuous circu1n'fer ential shoulder constituting the upper end of a neck enlargement, a head ot' less diameter than said neck and bayonet-joint grooves beginning in the shoulder and terminating in the enlargement, with a cap provided with a similar shoulder, and lugs below the capshoulder to engage said bayonet-joint grooves, said lugs being integral with the cap-flange and comprised between tivo slits therein, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.

PHILIP LINDEMEYR.
